摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device of a new system, which has a wide viewing angle. SOLUTION: The liquid crystal display device includes: a first substrate 10 and second substrate 20 facing each other; a liquid crystal material layer 70 vertically aligned initially, which is injected into between the first and second substrates; and a means for changing a major axis direction of molecules of the liquid crystal material layer. The liquid crystal material layer has two regions adjacent to each other. In the two regions, liquid crystal molecules are arranged mutually in different directions. The molecules, which belong to any one region among the adjacent regions, are arranged symmetrical with regard to the boundary between the two regions. The difference between the drive voltage obtained when a light passing through the liquid crystal material layer has the largest light transmittance and the drive voltage obtained when the light has the lowest light transmittance is ≤30 V.

摘要： A liquid crystal device comprises two electrodes 30,40 parallel to each other formed on one 10 of two substrates 10,20, homeotropic alignment films 90 formed on the substrates and a liquid crystal material 70 having positive dielectric anisotropy injected between the substrates. When a voltage V is applied to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the generated electric field is symmetrical with respect to the boundary-plane equidistant from each of the two electrodes, the liquid crystal molecules 80 are symmetrically aligned with respect to the boundary-plane, and the optical characteristic is compensated in both regions divided by the boundary-plane, thereby obtaining a wide viewing angle. The electric field does not exert any influence on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrate and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. The device also comprises means for varying directions of long axes of molecules of the liquid crystal layer, wherein the layer has at least two adjacent regions, the molecules of any one region being aligned in the same direction, and the molecules of two regions are aligned symmetrically with respect to the plane-boundary of the regions. The parallel electrodes in each pixel unit may be bent, and in adjacent pixels may be in different directions.

The electric field does not exert any influence on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrates and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. Here, the polarization of the light is changed while passing through the liquid crystal layer 70 and as a result, only a part of the light passes through the polarizing plate. The transmittance of the light can be varied by controlling the magnitude of voltage V applied to the two electrodes.
